Kryger [21]

Answer:

1. Element - a substance that is made from only one type of atom

An element is made up of only one type of atoms and known for its unique properties than other elements.

2. Heterogeneous - composed of dissimilar parts which can be separated easily and which are unevenly distributed in the mixture

3.Homogenous - even distribution of parts throughout the whole mixture; not easily separated into individual components.

4. Product - the substance created as a result of a chemical reaction

Products are the final substance that created as a result of a chemical reaction.

5. Reactant - one of the starting substances (ingredients) that is involved in a chemical reaction

Reactants are the starting substance that takes part in a chemical reaction.

6. Solute - the substance that is being dissolved.

A Solute is a substance that is being dissolved in the solvent to make a solution.

7. Solvent - the substance that does the dissolving

A solvent is the medium in which the solute is being dissolved to make the solution.

Answer:

$\large \boxed{\text{0.1767 mol/L}}$$

Explanation:

(a) Balanced equation

3NaOH + H₃PO₄ ⟶ Na₃PO₄ + 3H₂O

(b) Moles of NaOH

$\text{Moles of NaOH} = \text{34.52 mL NaOH} \times \dfrac{\text{0.3840 mmol NaOH}}{\text{1 mL NaOH}} = \text{13.26 mmol NaOH}$

(c) Moles of H₃PO₄

The molar ratio is 1 mol H₃PO₄:3 mol NaOH.

$\text{Moles of H$_{3}$PO}_{4} = \text{13.26 mmol NaOH} \times\dfrac{\text{ 1 mmol H$_{3}$PO}_{4}}{\text{3 mmol NaOH}}\\\\= \text{4.419 mmol H$_{3}$PO}_{4}$

(d) Molar concentration of H₃PO₄

$c = \dfrac{\text{moles of solute}}{\text{litres of solution}}\\\\c = \dfrac{n}{V} = \dfrac{\text{4.419 mmol}}{\text{25.00 mL}} = \text{0.1767 mol $\cdot$ L$^{-1}$}\\\\\text{The molar concentration of the NaOH is $\large \boxed{\textbf{0.1767 mol/L}}$}$
